Injection tetanus toxoid: what to know

Tetanus is caused by bacteria entering damaged skin, particularly a deep, dirty or puncture wound. Tetanus toxoid is an inactivated component used in vaccination; it trains immune memory and does not remove dirt or bacteria from an injury. A clinician checks the wound and your record to decide whether vaccination, wound care or another treatment is needed.

The injection may leave temporary soreness, redness or swelling. Feeling tired or having a mild fever can also occur. These reactions are different from tetanus, which can cause painful muscle stiffness, difficulty opening the mouth or trouble swallowing.

Rinse a wound with clean running water, apply gentle pressure for bleeding and cover it with a clean dressing. Arrange medical assessment promptly for a deep, dirty, crushed or bite wound, or if an object remains inside. Take any vaccination record you have and explain when and how the injury happened.

Complete the recommended vaccination schedule if further doses are advised. Keep the dressing clean, follow wound-care instructions and do not inject a product obtained from an unverified source.

Seek emergency help for uncontrolled bleeding, loss of feeling or movement, a serious bite, a wound involving the eye or face, or signs of a severe allergic reaction such as breathing difficulty, throat swelling or collapse. Seek urgent care for increasing redness, warmth, swelling, pus, fever or worsening pain around the wound.

Ask whether the wound needs cleaning or closure, whether your vaccination record changes the recommendation, how many follow-up doses may be needed, and which infection signs should prompt a return visit.
